Special Order




RESU10H - 9.8kWh high voltage battery storage system

This battery from LG Chem is a Residential Energy Storage Unit (RESU) featuring a 400V lithium ion battery with integrated battery management system.

The RESU10H is designed to tie in with a grid connect solar system to increase self-consumption and savings. An additional high voltage inverter (SMA Sunnyboy Storage) is also required. 9.8kWh is big enough to offset the late afternoon/evening energy use of an big Aussie household. It may even cover evening and early morning electricity needs.

This battery features 5000 watts continuous power and DC round-tripefficiency of 95% while ensuring 80% of capacity retention after 10 years, and consequently comes with a 10 year warranty.

All LG Chem RESU models are floor or wall mountable; the protection class (IP55) even allows outdoor installation; however, RPC recommends a cool location, e.g. inside a brick garage.
